Welcome in H.C.M.
I have gone through your query regarding sore throat
, stone in tonsils and itching in both ears.
Since your tonsils are having stone therefore permanent remedy is only operation but as you said that you are a liver
transplantee so preoperative fitness for operation and anesthesia
is must from physician.
If your general condition is not fit for major surgery than you may consult your ENT doctor for tonsillectomy
Laser and coblation are modalities of operation having least post operative pain and are bloodless procedure.
If nothing above is possible than only stone removal from tonsil may be done and that will give only temporary relief.
I hope your query is answered.
